FlRE-GRATE FOR FIRE-PLACES.

SPECIEIGATIQN forming part of Letters Patent No. 367,793, dated August9, 1887. Application tiled April 10, 1887. Serial 310.234.9512. (Nomodel.)

To all whom it may concern Be it' known that we, HENRY G. DAWSON andWILLIAM R. DAwsoN, of Chicago, Illinois, have invented certain new anduseful Im- 5 provements in Fire-Grates for Fire'Places or Furnaces, ofwhich the followingis aspecificatiOn. v

The invention relates to means for clearing the grate; and it consistsofa sliding head supported beneath the grate and provided with spurs orbeveled teeth projecting between the parallel bars, and adapted toagitate the coal above as the head is moved back and forth. Y

The accompanying drawings illustrate the invention. 7

Figure 1 is atop view of a common fire-place grate with the cleanerattached. Fig. 2 is a bottom view of the same. Fig. 3 is a section online :0 x of Fig. 2, looking toward the left. Fig. 4 is a centralsection of Fig. 2 on line 00 as. Fig. 5 is a section of the gratewithout its frame on line 11 y of Fig. 2. Fig. 6 is a perspective ofadetail, showing a modification.

A designates the frame of the grate.

B is the grate provided with open parallel slots I). The grate ispivoted to the frame at a, so as to be dumped. At the front edge itrests on ledges or stops to on the frame, and is provided with aslidingbolt, 1), adapted to catch under the frame to prevent accidentaltilting.

The parts thus far described are of ordinary construction. 7

Cis the rod or head, which is supported immediately beneath the grate inslots or ways a,

so as to slide back and forth under it, and proin contact with the coal.As the head is moved back and forth the spurs will rotate and agitatethe bottom layers of coal, thus causing the ashes to be separatedtherefrom and fall through the grate.

Fig. 6 shows the head 0 provided with rigid teeth 0, adapted to passbetween the slots of the grate and agitate the coal as the head is movedback and forth. This form may be used in place of the one provided withthe spur-wheels; but the latter is the preferable one.

WVhat we claim is- 1. The combinationgwith a grate, B, of a sliding headsupported under the grate, and provided with teeth projecting throughthe slots b and movable therein, substantially as specified. w

2. The combination, with a grate, B, of a sliding head, G, provided withrotary spurwheels 0 projecting through the slots b and movable therein,substantially as specified.
